NEWS HIGHLIGHTS

Improving Safety of Antivenom in People Bitten by Snakes [Completed]
A study to increase the safety of polyvalent antivenom involving 1000 patients in three
centres: low dose adrenaline, promethazine, & hydrocortisone (alone and in combination) to
prevent acute adverse reactions to antivenom in people bitten by snakes: randomised, double
blind, placebo-controlled trial.

Prevention of Narcotic-Induced Nausea [Terminated]
We are doing this study to find out if extra medicine is needed to avoid the chance of
nausea sometimes linked to narcotic pain medicine (for example, morphine, dilaudid,
fentanyl). Some doctors always give medicine to prevent the possible side effect of nausea,
while others do not. We are looking to see if this extra medicine is helpful in preventing
nausea. The goal is to screen all patients with pain and enroll enough subjects to reach
our goal of 164 evaluable study participants.

Effect of Hyoscine and Promethazine on Labor Pain [Completed]

investigators decided to compare of effect of hyoscine N-butyl bromide and Promethazine on
length of active phase of the first stage of labor.
